Niji No Sora Intro tab by FLOW

Tabs

This tab is incomplete, obviously, and was created by listening to https://www.youtube.com/watch?v=outx6ZPOP8U.
I just haven't gotten around to figuring out the main bulk of the song.
I intend to tab out the rest as soon as I can. Any comments would be very helpful and
very much welcomed.
